A control apparatus for controlling electrical switchgear, the control apparatus being designed such that it is capable of performing the following in succession:

Apparatus for controlling electrical switchgear

An arrangement for synchronizing and the actuation of a set of three interrupters, tow of which are disconnectors and one is a switch, in a combined circuit breaker and disconnector for an alternator is described. This allows for fitting of an accessory shaft for actuation purposes, which is specifically dedicated to the actuation of one of the two disconnection interrupters and to set it in rotation only after a final angle of rotation of a main shaft, which is itself dedicated to the actuation of the other disconnecting interrupter and actuation of the switching interrupter.

Combined circuit breaker and disconnector for an alternator with actuation by an assembly of a main shaft and secondaries shafts

Operating mechanism for medium and high voltage switchgear, in which a rotatable main shaft is coupled to a switch, and a rocker plate is rotatable with the main shaft, the main shaft being arranged to open and close said switch by tilting the rocker plate. The rocker plate constitutes a plurality of force transmission levers and comprises a plurality of zones distributed around the main shaft. A rotary actuator has force transmitting means for driving the rocker plate in a direction corresponding to closing of the switch, and an opening spring for driving the rocker plate in a direction corresponding to opening of the switch. Closed switch locking means are coupled to the rocker plate () and are disposed substantially in a common plane of the rocker plate.
